Dear Steve,
Thanks for contacting Top China Travel!
The volunteer program in Dujiangyan Panda Valley has reopened since March 24, 2015 and it is the only panda base providing the volunteer program now. The volunteer program in Dujiangyan Panda Valley allows visitors to take pictures for 5 mins, but holding a panda is still suspended in all panda bases (including Dujiangyan Panda Valleyt, Bifengxia Giant Panda Base, Chengdu Giant Panda Breeding and Research Base), and the reopening date is TBA.
Any further request or question, please feel free to contact with us.
